California law requires workers compensation insurance for every business with W-2 employees. There are no exceptions for small companies, new companies, or companies where the work seems low-risk. Trucking is not low-risk. Driving commercial vehicles is one of the most hazardous occupations from an insurance perspective, and the premiums reflect that.

Your premium is based on classification codes assigned to the type of work your employees perform. Truck drivers fall under specific codes (like NCCI code 7219 for long-haul or 7228 for local deliveries) that carry some of the highest rates in workers comp. The rate is applied per $100 of payroll, so the more you pay drivers, the more your premium costs. A trucking company with $500,000 in annual driver payroll can easily face $40,000 to $80,000 or more in workers comp premiums depending on the classification and the company’s claims history.

Your experience modification rate (or “mod rate”) matters a lot here. New companies start at 1.0, which is the baseline. If you have a clean claims history over time, your mod drops below 1.0 and your premiums decrease. If you have frequent or severe claims, your mod goes above 1.0 and you pay more. For freight and logistics companies, managing safety programs and minimizing workplace injuries directly impacts the bottom line through lower premiums.

Owner-operators leased onto a carrier create a different situation. If they are truly independent, operating under their own authority or their own insurance, they may not need to be covered under your policy. But California applies strict tests for independent contractor status under AB5. If an owner-operator is working exclusively for you, using your dispatch, and following your schedule, the state may consider them your employee regardless of what your contract says. And if they’re your employee, you owe workers comp on their earnings.

This is where misclassification becomes a serious financial risk. Some trucking companies classify drivers as 1099 independent contractors specifically to avoid workers comp premiums, payroll taxes, and other employment costs. California’s Employment Development Department actively audits trucking companies for this. If EDD determines your “contractors” are actually employees, you owe back payroll taxes, penalties, and interest. You also face exposure for unpaid workers comp premiums, and OSHA penalties can stack on top of that. The savings from misclassifying drivers almost never outweigh the cost of getting caught.

Your workers comp insurer will audit your payroll records annually to verify that premiums were calculated on accurate numbers. If your actual payroll was higher than what you estimated when the policy started, you’ll owe additional premium at audit time. This is why accurate payroll records and proper employee classification matter from day one. Keeping your books clean throughout the year prevents surprises when the audit hits.
